WILLIAM L. PAUL, OF SOUTH BEND, INDIANA, ASSIGNOR- TO OLIVER CHILLEDPLOW WORKS, OF SOUTH BEND, INDIANA.

PLOW.

To all whom 2'25 may concern:

Be it known that I, WILLIAM L. PAUL, of South Bend, in the county of St.Joseph and State of Indiana, have invented certain new and useful,Improvements in Flows; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as Wlll enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvement in plows and more particularly tothat type known in the trade as engine gang plows.

One object of the invention is to provide a plow structure comprising aplurality of units, each embodying a truck frame and a plurality ofplows, and to so construct such units that they shall be capable ofseparate use or so that they can be readily connected and operated inany desired manner.

A further object is to so construct an engine gang plow structurecomprising a plurality of connected units or sections, that thesectional framework embodying such units or sections shall be capable offlexing in two directions at substantially right angles to each other topermit the plow structure to adapt itself to the conforma-.

tion of the ground.

A further object is to so connect two or more units or sections of aplow structure,

that said units or sections shall be capable of pivotal movement in twodirections rela tively to each other.

With these and other objects in view the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of an engine gangplow structure embodying my invention. Fig. 2 is a side elevation of thesame showing only two plow beams and the devices which cooperatetherewith, and Figs. 3, 4, and 5 are detail views.

My improved plow structure comprises a plurality of units, two of suchunits, 1 and 2 being shown in Fig. 1 of the drawing al though it isapparent that any desired num ber of such units may be employed and eachof said units is the same in construction. Each unit comprises a truckframe or sec tion 3 and a series of plows having their beams 4 connectedwith said truck frame.

Specification of Letters Patent.

Application filed July 12, 1910.

Patented Feb. 18,1913. Serial No. 571,649.

Each truck frame has a general triangular shape and comprises an angleiron member 5 to be disposed at an angle of 45 degrees more or less tothe direction of travel of the plow; an angle iron member 6 secured atone end to the member 5 near the end of the latter and projectinglaterally therefrom so as to be disposed at right angles to thedirection of travel or line of draft of the machine, and an angle ironmember 7 secured at one end to an intermediate portion of the member 6and at its other end to the diagonal member 5 near the end thereofopposite to that to which the memher 6 is secured. A brace '8 extendsfrom the member 5 to the member 6 and a similar brace 9 extends from thefree end of the member 6 to an intermediate point on the member 7 At thefree end of the member 6 of the truck frame (which in effect constitutesthe apex oi the triangular truck frame) a bracket 10 is secured for theaccommodation of the swiveled frame 11 of a truck wheel 12.

A series of brackets 13, located at intervals on the diagonal member 5of the truck frame unit, project rearwardly from said member 5 and toeach of these brackets, a longitudinally adjustable knuckle 14 issecured and adapted for pivotal connection of a plow beam 1 therewith.Each plow beam progressively from one end of the series of plow beams tothe other. A laterally projecting brace 15 is secured to an intermediateportion of each plow beam and at its forward end, each brace 15 isconnected with the angle member 5 of the truck frame unit by means of avertically adjust-able knuckle 16. A soil engaging member 17 is locatedat the rear end of each plow beam. By connecting the forward end of theplow beam with the truck frame unit through the medium of thelongitudinally adjustable knuckle 1 1, I am enabled to regulate theangular relation of the plow to the truck frame unit, thereby changingor adjusting the distance between various plows. Vith the use of thevertically adjustable knuckle 16 with which the brace 15 is connected, Iam en abled to level a plow relatively to the frame and to the otherplows of the series.

The end brackets 13 on each truck frame unit are provided withrearwardly project ing members 38 with which frames 39 are pivotallyconnected and these frames carry gage wheels 40. These gage wheels arethus located rearwardly of the pivotal connections of the adjacent plowbeams with the truck frame unit and serve to gage the height of theforward ends of all the plow beams of the series and serve to give moreuniform plowing than if said gage wheels were placed forwardly under thetruck frame atsome distance ahead of the point of the plow.

Each truck frame unit is provided at one end with a forwardly projectingarm 41 and at the other end with an L-shaped arm 42, said arms beinglocated at respective ends of the member 5 of thetruck frame unit. Twounits are placed together so that their members 5 will be in alinementwith each other as shown in Fig. 1 and the arm 41 of one unit disposedparallel with the free member of the L-shaped arm 42 of the ad jacentmember. The arms 41 and 42 of adjacent members are loosely connectedtogether by means of a bolt 43, the connection being sufficiently looseand permitting suf ficient play to allow the plow units or sections toflex relatively to each other in two directions substantially at rightangles to each other and thus permit the plow structure to readily adaptitself to the contour of the ground over which the plow is working.

To the free end of the member 6 of each truck frame unit, a bracket 44is secured and the bracket 4 of one truck frame unit is connected withthe bracket 44 of the adjacent truclr frame unit by means of a rod orlink 45 the respective ends of which are provided with hooks 46 toloosely engage in holes in the brackets 44 of the respective truck frameunits.

A platform member 47 is located on each truck frame unit and securedthereto by means of bolts e8. The respective ends of each platformmember 47 are beveled and the triangular space between the platformmembers on adjacent truck frame units is closed by a triangular platformmember 49 which is connected at one edge by means of hinges 50 with theplatform member on one truck frame unit and supported at its oppositeedge by means of a hanger 51 which engages the platform member 4L7 onthe adjacent truck frame member. Thus a continuous platform is providedfrom end to end of the plow structure and is so constructed as not tointerfere with the flex ing of the plow unit.

The members (5 of the truck frame unit are provided with perforations asshown at 52 to facilitate the attachment of chains or other draftdevices by means of which the plow structure can be connected with atraction engine.

Having fully described my invention what I claim as new and desire tosecure by Let tors-Patent, is,-

1. A gang plow structure, comprising a plurality of plow units, meansconnecting said plow units in a manner to permit them to flex verticallywith relation to each other in directions about axes respectivelyapproximately parallel with and at right an gles to the line of draftand means connect ing said units and preventing appreciable horizontalrelative movement.

2. A gang plow structure, comprising a plurality of plow units, meansconnecting said plow units in a manner to permit them to flex verticallywith relation to each other in two directions about horizontal axes,respectively, approximately parallel with and at right angles to theline of draft and means connecting the forward portions of said unitsand preventing appreciable horizontal relative movement.

3. A gang plow structure, comprising a plurality of units, each unitcomprising a truck frame and a plurality of plows connected therewith,means connecting the truck f 'ames of adjacent units in a manner topermit the units to flex Vertically in directions about axes,respectively, approximately parallel wit-h and at right angles to theline of draft and a rigid bar connecting the forward portions of saidunits.

4. A gang plow structure, comprising a plurality of units, each unitcomprising a truck frame and a plurality of plows connected therewith,said units being so disposed that the portions of the truck frames withwhich the plows are connected will be disposed in alinement with eachother, means loosely connecting adjacent ends of the alined portions ofthe truck frames, and means loosely connecting the forward portions ofadjacent truck frames,whereby said units can flex vertically withrelation to each other in directions about axes, respectively,approximately parallel with and at right angles to the line of draft.

5. A gang plow structure, comprising a plurality of units, each unitcomprising a substantially triangular truck frame and a plurality ofplows connected therewith, means loosely connecting the triangular truckframes with each other so as to dis pose their hypotenuses in anapproximately straight line, and means loosely connected at respectiveends with the forward portions of adjacent truck frames.

6. In a gang plow structure, the combination of a plurality of units,each comprising a triangular truck frame and a plurality of plowsconnected therewith, means loosely connecting the triangular truck frameunits so as to dispose their hypotenuses in a substantially straightline, means loosely connecting forward portions of adjacent truck frameunits, and supporting wheels for the forward portions of said truckframe units, of a platform member secured upon each truck frame unit andan intermediate platform member hinged to the platform member on onetruck frame unit and loosely supported by the platform member on theadjacent truck frame unit.

7. A gang plow structure, comprising a plurality of successive units,each unit comprising a truck frame and a plurality of plows connectedtherewith, means loosely connecting the adjacent ends of adjacentframes, and means loosely connecting the forward portions of adjacentframes, whereby said units can flex Vertically relatively to each other,about axes respectively approximately parallel with and at right anglesto the line of draft.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
